National Grid plc (NGG)

RSI 14

Momentum gauge, 0–100. A low reading describes losses dominating recent gains; it does not predict a reversal. Recomputed at the what-if price from the served daily tape.

vs 50-day

The average close across 50 sessions. Trading at or below it describes price location versus the recent trend; it is not evidence that buyers will defend the line.

Bollinger

A 20-session volatility envelope. A lower-band pierce describes an unusually low price relative to that recent distribution; it does not guarantee mean reversion. The band re-forms around the what-if price.

VWAP 20

A 20-session rolling VWAP approximated from daily typical price and volume, not an intraday session anchor. Being below it is a price-location descriptor, not a forecast.

Entry level

The entry reference published by the audited level composer from the stock's support zone. It is a model level, not an instruction or guaranteed floor.

Put wall

The strike with the largest put open interest in the stored chain snapshot. It is an options-positioning reference, not verified price support.

MACD

Momentum-shift gauge shown as context, not part of the alignment rule. Recomputed at the what-if price when the served daily tape is usable.

RVol

Volume so far today, projected to a full session, against this name's own average over the last 20 sessions. Above about 1.5x is unusually active for this name and below about 0.7x unusually quiet; heavy volume says a lot of shares changed hands, never which way the next move goes. A hypothetical price cannot create volume, so this tile holds steady as the slider moves.

Short int.

Shares sold short as a percentage of float. The 20% threshold is a crowding descriptor, not a forecast of a squeeze. This value updates on the reporting cadence.

ATR

Average true range describes the stock's recent daily price range. It is informational and does not enter the alignment count.
